Intermittent internet connection

Pulse · 2 Aug 2007 at 00:16

can someone have a look at these figures and tell me if there is anything dodgy? cos there is nothing to suggest a correlation between time of day and disconnection or noise/line attenuation and disconnections, not environmental, can be amazing hot or cold or shocking when hot or cold. had the same problems with 2 different ISP's, Tiscali and now with Sky, 2 different routers, belkin and now netgear. different internal cables, new ones were installed by BT shortly before we left tiscali and our problems continued and we thought it was tiscali.

but that only left the cables between our house and the exchange and the exchange itself. i have contacted BT and they have said that there is no problem with the exchange which i dno whether to believe or not considering how much bull they talk..

but here is some of the readings i have taken recently and would appreciate if someone could have a quick look through them.

hope you can understand that

Looks like a bad intermittent fault on the line. Is there any noise on the voice side of it? Are those stats from the master socket?

Pulse · 2 Aug 2007 at 02:36

yer there is some crackling on the line almost constantly. and no its not, if i plug it into the mast socket i would have to take the face plate off due to the face plate being a filter and plug it all into the test socket.

Definitely sounds like noise on the line. Need to test from master socket.

Pulse · 2 Aug 2007 at 02:44

hmm ok

spose that gives me something to do tomorrow

check if theres still noise connected to the master socket! If there is ring bt and report a voice fault on the line, when that gets fixed (which it should be fairly quickly) the broadband should be much happier as well

after some testing i've got some conclusive results - the problem is not within my house.

i started in my bedroom where i actually have 2 phonelines, one used to be used for both phone and router by using a filtered faceplate but after we had a BT engineer round here installed a second line to my bedroom dedicated for the internet connection (no standard phone input). the problem still consists on both lines, so i thought it my have just been dodgy connections. so i thought i would check the master socket last...

Alas i went downstairs to the kitchen tried there used 2 different cables from the router to the filter to make sure it wasnt that, tried 3 different filters; wasnt that, made sure it was the only thing connected at the time. everything. although the master socket does have a BT filtered faceplate i was smart enough to remove that and plug the kitchen extention into the test socket so that it wouldnt be double filtered. i carried out the same tests in the computer room where there is another extention with same results 10 failed connections. again i made sure that this extention was the only one connected and into the test socket. i then got round to the master socket. i put the offical faceplate back in plug in a little wired phone and tested it, although the phone was crystal clear when i connected the router there was absolutely no connection. i could hear it dialing but then it would just drop as if it wasnt finding anything. took the faceplate off and tried the router with all 3 microfilters same thing, no connection but phone was crystal clear.

so i have tested now every socket in the house with every cable and filter combination possible. disconnected all the other lines and tested singuly, tested with all lines plugged in, with sky without sky, with additional phones without.. and no different. i give up come up stairs to my bedroom plug everything back in how it was before i started, and it connects 1st time, WTF? :confused:

so there is no pattern with this and it is apparently nothing to do with what i have done in the house so god knows. there is a new service offered by BT which tells you which exchanges are having problems, so i rang that number and it suggested one exchange which i have no idea where that is but obviously it makes no difference to me as no-where near.
